This is an amazing article from "Journal of American Folklore," which is a peer reviewed, professional journal. The articles most often disclose their sources and it's fairly clear that this is documented testimony of historians etc. And they aren't hard to read, in my opinion.
In this article about the people of the Salish of Puget Sound, the words of songs are detailed, AS WELL AS the notation of them are shown, so the songs can still be sung by by those who wish. Nice going, archive.org. It's perhaps the case that with this article you've saved a part of history.
